Biomedical Imaging and Devices

Biomedical imaging is one of the most important tools for investigating anatomy, physiology, and function at multiple levels from cellular to the whole body.

At Mason Bioengineering, we are combining multiscale imaging, including new ultrasound, photoacoustic, and magnetic resonance imaging techniques with novel devices for modulating function, including transcranial magnetic stimulation, ultrasound induced bioeffects, and assistive technologies for rehabilitation.

Our areas of expertise include:

Ultrasound imaging and devices

This research investigates brain-body interactions through imaging. In particular, we are studying the interactions between the central and peripheral nervous system and the musculoskeletal system in a number of clinical conditions of major public health significance, such as chronic pain, stroke, spinal cord injury, and amputation.

Ongoing research includes the development and evaluation of novel bionic technologies, such as upper extremity prostheses and hybrid exoskeletons, using wearable imaging sensors for sensing the human user’s volitional intent. This approach can significantly improve the functionality of advanced prostheses and exoskeletons. Principal investigator: Siddhartha Sikdar.

Photoacoustic imaging and microscopy

Photoacoustic imaging is a hybrid imaging technique that combines the spectroscopic specificity of optics with tissue penetration of ultrasound. Our group focuses on novel implementations of photoacoustics for (1) non-contact microscopy of retinal vasculature, and (2) mapping cerebro-vascular function and neuro-electrical activity in the brain with the long-term goal of gaining insights into brain function and neurodegenerative diseases. Principal investigator: Parag Chitnis.
